I just bought a copy recently as well, ordered about 2 weeks ago...
At the time I bought it, there were two listings for the 3rd edition deck: one was a pre-order, the other wasn't. If you look at the etsy reviews, you'll notice these differences in the title. I bought the one that wasn't a pre-order and there were only two of them left in stock at the time that I purchased (judging from the drop down menu where you select the quantity).
Both listings said that issues with blurriness have been fixed, but the pre-order said something about the borders being more cleaned up (those aren't necessarily the exact words she used; I'm going off memory).
It appears that she just updated the listings for her deck and it doesn't say "pre-order" anymore (there's only one listing for the 3rd edition right now; the pre-order listing isn't available anymore, and the other non pre-order listing seems back in stock)... My guess is that there was another print run (the pre-order) and maybe she replenished her stock? I am really, really not sure though, so please take that as speculation rather than observation... But the fact that the pre-order listing had said something about the borders and the other didn't made me wonder if there were possible quality differences across the 3rd version decks/print-runs. Again, I didn't purchase the pre-order and on mine the borders are not perfect. So if there was indeed an updated run (with some change to this), I don't think that's what I got.
Are any cards particularly more grainy than others? As in, how does the image quality of the unchanged cards compare to the 21 updated cards where she changed the art? On mine, the updated cards are more crisp looking in comparison to the other cards that hadn't been changed (which are definitely way more fuzzy). Because of that, I assumed that this is the way it was meant to be and that this is just how the deck is up-close. Am I wrong? I am quite happy with my deck anyway because I presumed that this was normal. Maybe not!!
I still, however, adore the copy that I have. Although upon receiving it, I did think, "Hey, wait a second..." as I noticed the slight fuzziness across the unchanged cards. My heart nearly sank as I was afraid that maybe there was something wrong with my deck (thinking that perhaps I should have gotten the pre-order)... But as I fanned through the cards and held them in my hands, it started to bother me less and less. Call me crazy, but I started to fall in love with the messiness. At that moment, I felt the imperfections added to the charm, giving it a very magical homemade feel... also making the cards seem much older than they are. I love the slight sepia tone for that as well...
But if there is a quality issue that I'm not aware of, then that would be disappointing considering the higher price she's selling them for now. I don't have any other deck of hers to compare to. If I ever buy another 3rd edition in the future, maybe then I'll be able to say...
